Given numbers are 617,800,430,805,790

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 617,800,430,805,790 is 269958231200.

Find LCM of 617,800,430,805,790 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 5 x 617 x 80 x 43 x 161 x 79 = 269958231200

Therefore, the lowest common multiple of 617,800,430,805,790 is 269958231200.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

617 x 800 x 430 x 805 x 790 = 134979115600000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

617 : 1, 617

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

430 : 1, 2, 5, 10, 43, 86, 215, 430

805 : 1, 5, 7, 23, 35, 115, 161, 805

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,800,430,805,790, is 1.

Now, the common factors can be found like this.

617:617

800:2x 2x 2x 2x 2x 5x 5

430:2x 5x 43

805:5x 7x 23

790:2x 5x 79

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 5x 5x 5 = 500

Therefore, the value for common factors is 500.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 134979115600000/(1x500)

LCM = 134979115600000/500

LCM = 269958231200

Thus, we can understand that the LCM of 617,800,430,805,790 is 269958231200.
